    摘要： Methods and systems for infusing ceramic proppant and infused ceramic proppant obtained therefrom are provided. The method can include introducing ceramic proppant and a chemical treatment agent to a mixing vessel, mixing the ceramic proppant and the chemical treatment agent in the mixing vessel to provide a mixture, introducing microwave energy to the mixing vessel to heat the mixture to a temperature sufficient to produce infused ceramic proppant containing at least a portion of the chemical treatment agent, and withdrawing the infused ceramic proppant from the mixing vessel.

    摘要： Methods and systems for determining subterranean fracture closure are disclosed herein. The methods can include electrically energizing a casing of a wellbore that extends from a surface of the earth into a subterranean formation having a fracture that is at least partially filled with an electrically conductive proppant and measuring a first electric field response at the surface or in an adjacent wellbore at a first time interval to provide a first field measurement. The methods can also include measuring a second electric field response at the surface or in the adjacent wellbore at a second time interval to provide a second field measurement and determining an increase in closure pressure on the electrically conductive proppant from a difference between the first and second field measurements.

    摘要： Methods for manufacturing electrically-conductive proppant particles are disclosed. The methods can include preparing a slurry containing water, a binder, and a raw material having an alumina content, atomizing the slurry into droplets, and coating seeds containing alumina with the droplets to form a plurality of green pellets. The green pellets can be contacted with an activation solution containing at least one catalytically active material to provide activated green pellets including the at least one catalytically active material. The method can include sintering the activated green pellets to provide a plurality of proppant particles. The plurality of proppant particles can be contacted with a plating solution containing one or more electrically-conductive material to provide electrically-conductive proppant particles.
